Reversi Game in LabVIEW

A fully-featured implementation of the classic Reversi board game in LabVIEW, featuring both local play and online multiplayer capabilities.

Features

• Classic Reversi/Othello gameplay on an 8x8 board
• Player vs. Computer mode with AI opponent
  • AI implemented using minimax algorithm with heuristic evaluation
  • Multiple difficulty levels via search depth
• Online multiplayer mode (client-server architecture)
• Beautiful graphical interface

Project Structure

The project is organized into the following components:

Main VIs

• main.vi - Main game interface for local play
• client.vi - Client interface for online play
• server.vi - Server application for hosting online games
• online(client1st).vi - Online game where client moves first
• online(server1st).vi - Online game where server moves first

Game Logic (subvis.lvlib)

• availablePlaces.vi - Identifies valid move locations
• countResult.vi - Tallies the score
• heuristic.vi - Evaluates board positions for AI
• isEnd.vi - Determines if the game has ended
• minimax.vi - AI decision algorithm
• randomMove.vi - Random move generator
• takeStep.vi - Executes a game move

Board Visualization (drawPlate.lvlib)

• canBePlaced.vi - Verifies if a piece can be placed at a position
• initialize(picture).vi - Sets up the initial board
• putPiece(picture).vi - Places a piece on the board

Requirements

• LabVIEW 2022 or later
• TCP/IP connectivity for online play

Getting Started

1. Open othello.lvproj in LabVIEW
2. Run main.vi to play locally or:
   • Run server.vi on the host machine
   • Run client.vi on the connecting machine

Game Rules

Reversi (also known as Othello) is played on an 8×8 board with discs that are black on one side and white on the other.

• Players take turns placing discs on the board with their assigned color facing up
• To make a valid move, a player must place a disc such that it creates a straight line (horizontal, vertical, or diagonal) between the newly placed disc and another of their discs, with one or more of the opponent's discs in between
• All opponent's discs that are in this straight line are flipped to the current player's color
• If a player cannot make a valid move, their turn is skipped
• The game ends when neither player can make a valid move
• The player with the most discs of their color on the board wins

Development

This project uses LabVIEW's native libraries for GUI rendering and TCP/IP communication for networking functionality.
